Hi Martin
I’ve just upgraded to 14.1 but the problem is still there.
I’m not actually exporting tracks, this is occurring during tracking.
I’ve just taken a couple of screen shots from a test I’ve done post OS upgrade.
On the 1st screenshot you can see the waveform looks normal on both guitar tracks, however on playback I hear the audio drop out where the marker is showing (both guitar tracks, the drums play ok)
The 2nd screenshot shows the same project in the same location after I’ve saved it, closed cubase and reopened it… here it shows that the waveform is now flat, almost like a silence has been inserted
This final screenshot just shows an extra track which is an import of one of the wav files from the audio pool which shows that the wav form is missing there too
I do have logic so I can track using that instead, but I’ve used cubase for many years on a windows PC so more familiar with how to do what I need using Cubase.
Reading the other thread you posted, its possible this is another bug with Sonama and Cubase interoperability which will be a shame… might have to read up more on Logic Pro if I can’t resolve this as its not usable currently
